Thematic Bible: What cannot have communion together

Stop forming intimate and inconsistent relations with unbelievers. What partnership can right-doing have with law-breaking, or how can light participate with darkness? What harmony exists between Christ and Belial, or what is common between a believer and an unbeliever? And what agreement can a temple of God make with idols? For we are the temple of the living God, just as God said: "I will live in them and walk in them, and I will be their God and they will be my people."

I mean that what the heathen sacrifice they sacrifice to demons, not to God, and I do not want you to be in fellowship with demons. You cannot drink the cup of the Lord and the cup of demons. You cannot eat at the table of the Lord and at the table of demons.
